SPlNDLE AND BOLSTER FOR SPINNING-FRAMES.

SPECIFICATION forming part of Letters Patent No. 229,157, dated June 22, 1880.

Application filed March 18, 1880. (No model.)

To all whom it may concern:

Be it known that I, JAMES H. MAOKINTOSH, of Paterson, in the county of Passaic and State of New Jersey, have invented a new and useful Improvement in Spindles and Bolsters for Spinning-I rames, of which the following is a specification.

Figure l is a side elevation of the improvement. Fig. 2 is a sectional elevation taken through the line a: as, Fig. 1. Fig. 3 is a top view of the upper hearing, the second or cap whirl being removed. Fig. 4 is a side view of the bearing detached. Fig. 5 is a top view of the lower whirl.- Fig. 6 is a side view of the lower bearing. Fig. 7 is a top view of the lower bearing. Fig.8 is a cross-section of the lower bearing, taken through theline y 3 Fig. 6. Fig. 9 is a diagram illustrating a mode of driving the spindles. Fig. 10 is a side view of one of the whirls, showing the arrangement of the band.

Similar letters of reference indicate corresponding parts. i

The object of this invention is to furnish spindles and bolsters for spinning-frames so constructed that the spindles can be driven at a greater velocity thauis practicable with spindles constructed in the usual manner, which will allow the driving-band to be put on without detaching the whirl or bolster, and which will prevent the oil from being thrown out by centrifugal force.

A represents the socket, which is placed in the rail of the spinning-frame, where it is secured in place. Upon the lower end of the socket A is formed a screw, upon which is screwed a cup, B, to receive and support the lower end of the spindle O, and also serve as an oil-cup.

The cavity of the upper part of the socket A is enlarged to receive the lower bearing, D, and is countersunk at its upper end to receive the flange E, formed around the upper end of the said bearing D. In the upper end of the socket A is formed a notch, F, to serve as a spout for pouring in oil. The ,lower part of the bearing D has longitudinal flanges formed upon it, to rest against theinner surface of the sooketA and support the said bearing against the side pressure. a

G is the whirl, which receives the drivingband, and which has a tubular projection, H, formed upon its lower end, to enter the cavity of the flan ged upper end of the lower bearing, D. The whirl G has a screw-thread cut in its inner surface to receive a screw-thread out upon the spindle G, in such a way that the revolution of the whirl G, in driving the spindle C, may tend to screw the said whirl on.

Upon the upper end of the socket A is formed the lower end of the arm of the bolster -I, between the ends of which the whirl G is placed. The bolster l is made with a single arm, as shown in Fig. I, so that the drivingband can be put on and taken off without detaching the whirl G.

In the inner surface of the cavity in the. upper end of the bolster I is cut a screw-thread, to receive a screw-thread out upon the tubular projection J, formed upon the lower end of the socket K, which projection enters the countersunk upper end of the whirl Gr. Upon the spindle O is formed a cupflange, L, which enters the ring-cavity of the socket K, and the outer surface of which fits and rests against the inner surface of the upper bearing, M. The bearing M has longitudinal flanges formed upon its outer surface, to lit and rest against the inner surface of the outer wall of the socket K, and thus support the bearing M against the pressure of the spindle G.

The flanges upon the outer surfaces of the bearings D M leave spaces around the said bearings to receive oil. The lower edge of the bearing M is notched to allow the oil to pass beneath the said edge freely, and thus come in contact with the friction-surfaces of the spindle flange and bearing.

Upon the spindle G, at the upper end of the cup-flange L, is cut a screw-thread to receive the screw-thread out in the inner surface in the upper end of the second or upper whirl, N. The whirl N is countersunk from its lower end to receive the cup-socket K, as shown in Fig. 2, so as to bring the band which passes around the whirl N directly opposite the hearing M, so that the side draft from the said band may be resisted by the said bearing, to prevent the spindle from being drawn out of a vertical position by the said side draft from the said band.

With this construction the body of oil in the oil-cups remainsat rest, and is not thrown outward by centrifugal force from the revolving spindle 0. Any oil that may be carried up over the inner wall of the socket K, and may pass down the spindle O, escapes from the lower end of the tubular projection J into the countersunk upper end of the whirl G, where it is received in a ring recess, groove, or cavity, 0, formed around the said countersink, which groove 0 prevents the oil from being thrown out by centrifugal force from the spindle 0.

Through the body of the whirl G, and parallel with its inner surface, are formed anumber of holes, P, the upper ends of which open into the recess 0. The lower ends of the holes P are in the end of the tubular projection 11, formed upon the lower end of the said whirl G, so that any oil that may enter the recess 0 will pass through the holes P into the countersunk upper end of the lower bearing, D, where the said oil again comes in contact with the spindle O.

In the countersunk upper end of the bearing D is formed a ring groove, recess, or cavity, Q, to prevent the oil that enters the said countersink from being thrown out by centrifugal force from the spindle 0. Through the flange E of the bearin gs D are formed a number of holes, R, the upper ends of which open into the recess Q, and theirlower ends open into the space between the bearing D and the inner surface of the socket A, so that any oil that may enter the cavity- Q, passes down into the socket A and mingles with the oil already in the said socket. By this construction no oil can escape from the spindle to injure the material being operated upon.

The spindle shown in Figs. 1 and 2 is intended to be used singly or with a separate band in the frames now in general use, the whirl N acting simply as a cap to the oil-cup. When it is desired to use the spindle as a driver for driving the other spindles of the frame, the whirl G is removed and replaced by a larger one capable of receiving a large flat or. round leather or rubber band of suflicient strength to transmit through the shaft 0 the desired power to the whirl N, around which and the whirls of all the other spindles ,in contact are moving in the same direction and at the same speed.

The upper part of the spindle C may carry a bobbin, or it may run idle, or it may be cut off and the spindle be used only as a driver for the other spindles to give them an increased speed, and-thus cause them to do more work.

Having thus described my invention, I claim as new and desire to secure by Letters Patent l. A spindle and bolster, constructed substantially as herein shown and described, consisting of the rail-socket A, the cup B, the spindle U, the lower bearing, D, having countersunk, recessed, and perforated flange E Q R, the single-armed bolster I, the lower whirl, G, having a tubular projection, H, upon its lower end, a recessed countersink, O, in its upper end, and holes P formed through it, the socket. K, having tubular projection upon its lower end, the upper bearing, M, the cup-flange L, and the upper whirl, N, as set forth.

2. The combination, with the spindle 0, th rail-socket A, and the cup B, of the socket K, provided with the upper bearing, M, and having tubular projection J, the whirl Gr, having recessed countersink O in its upper end, holes P formed through it, and a tubular projection, H, upon its lower end, and the lower bearing, D, having countersunk, recessed, and perforated flange E Q R upon its upper end, substantially as herein shown and described, whereby any oil that may escape from the upper bearing-socket, K, will be conducted into the rail-socket A, and will be prevented from being thrown out by the spindle, as set forth.
